Which food item can be displayed in a self-service area without the use of packaging, sneeze guards, or a display case to protect them from contamination? A Sushi-grade fish B Nuts in shells C Cooked fish D Bulk deli rolls

B<br />Nuts in shells<br /><br />Nuts in shells can be displayed in a self-service area without the use of packaging, sneeze guards, or a display case to protect them from contamination. This is because nuts in shells are typically sold in their natural state and do not require additional packaging or protection from sneeze guards. Additionally, bulk deli rolls (option D) may also be displayed in a self-service area without packaging or sneeze guards, but they are not the best answer to this question. Sushi-grade fish (option A) and cooked fish (option C) should be protected from contamination to prevent the spread of foodborne illnesses, and therefore should not be displayed in a self-service area without packaging or sneeze guards.
